	First of all, your program won't run on many systems,
hoxna included, because that huge auto array you allocate won't fit
on the stack.  (We're not *all* running Amdahls, y'know).

	Second of all, well, you're right, "out of swap space", CRASH ! ,
isn't the most elegant way to handle it, but it seems to me if it happens
more than more than say twice, you've got malicious users or need to re-tune
your system.  But the only way I can see to do things differently would be
to kill the proccess asking for the fatal pages, and that could conceivably
cause just as many problems.
